By analyzing data from NASA's Chandra X-ray Observatory, Dutch astronomers have investigated a young, oxygen-rich supernova remnant known as G292.0+1.8. Results of the new study, published June 29 on the arXiv preprint server, yield important insights into the expansion of this remnant.

Collective agreements are least common where workers need them most

Workers earning the lowest wages are the least likely to be covered by collective agreements in Germany, despite being the group for whom these protections are arguably most important. In 2021, only 34% of workers in the lowest wage decile were covered by collective agreements, compared with more than 60% of workers in the middle of the wage distribution, according to findings of a new report by the ROCKWOOL Foundation Berlin (RFBerlin) and the Institute for Employment Research (IAB) in Nuremberg.

A dust storm on the Greek island of Crete in April 2026 - the WMO is calling for stronger sharing of sand storm data.

China and the southern United States were hit last year by some of their worst sand and dust storms in decades, the United Nations said Friday.

A research team synthesized and determined the structure of a borate-linked 3D crystalline covalent organic framework, TCTP-COF, via electron diffraction for the first time. These findings will help scientists determine the structure-property relationships for other 3D COFs and facilitate their tuning for advanced applications.

Overcoming many of society's biggest challenges requires innovations in materials chemistry to achieve specific goals: carbon sequestration to mitigate climate change, absorbing toxic chemicals for environmental remediation and delivering life-saving compounds to cure disease, for example.

A new study led by MIT researchers could drive the development of more energy-efficient digital displays—such as flat-screen TVs, augmented and virtual reality headsets, smartphone screens, medical imaging devices and even large-area ambient lighting surfaces—that also generate richer, brighter colors.

Ancient DNA challenges family assumptions in medieval Scandinavian graves

When archaeologists find adults and children buried together in medieval graves, it is often assumed that they were members of the same family. A new study from Stockholm University in Science Advances suggests otherwise.
